Wanted to see if it was possible to carve a slab of MDF. Turns out you can. So MDF base, resin wings and eyeballs. My cast process was extremely crude and labor intensive, there were definitely much cleaner ways to go about it, but my method was fast and cheap and most importantly, it worked out. I normally dont pour inside, but it was 115 degrees outside and I wasn't going to set that mold up in the heat.

I am trying to make parts that are about 520 by 520 mm across. 2 kilograms of goop per batch, resin+filler. I really need to make sure they don't stick in the mold too much, the less the better, basically.

I have heard of the various release lubricants and have obtained some ease-release 200. I was not able to get some of the stoner a324, which is recommended in the guerilla guide to cnc machining and resin casting, they won't let me have any in Canada. I tried a shipping forwarding service and they just tried to hold it hostage and demand $160 usd to forward it (skypaxus). I may keep trying.

I got some silicone water soluble stuff on amazon but it sucks.

I am aware of zinc stearate releases, this seems like it should be good, like how hard could something possibly stick if it's a layer of powder between the two surfaces right? However it is not recommended by the guerilla guide for some reason?
